About this app
CPG is a small app for when you need a chord progression and your brain is empty. Type what you’re going for. Pick a key, moods, and how hard you want it. CPG builds a chart you can play through on guitar or piano, hear in the app, save, and take with you. Guitar gets fret shapes. Piano gets voicings. You can tap through the progression, practice it, and export ChordPro or plain text. Premium unlocks more generations, longer charts, plus PDF and audio export.
